This is a cross post with the Rokkor thread. 250mm 5.6 on the A7r.
I suppose this is mostly about the lens but I thought it might also be of interest on the A7r thread
Charlie, thank you for the kind words Wonderful set of images!
Yes the selection of 50's can be difficult. Having the 50 Lux Asph, 50 Cron DR and 50 Nocti f/1.0, including the FE 55 is great. You can experiment with the completely different styles of rending and looks.
So far, I am really pleased with the A7s, as it plays well with all these lenses.
Shots from this morning walk. A7s and 50 Noct f/1.0 @ f/1.0
While since I posted in this thread, been using my Leica more than my Sony. But, took the A7r and the Voightlander 12mm Heliar out to the 1872 Omaezaki Lighthouse and climbed the tower on one of the rare open houses. Sadly this is as close to the lens as I could get. The Third Order Fresnel Lens is lens is about 6ft (185cm) tall and can been seen over 20 miles away. Single raw file, processed with the Flat Field plug in.

I presume that is heavily cropped and de-vignetted? When I use the 12mm on an A7r I was seeing a dark circle around the edges!
Not cropped at all, but I did use Adobe Flat Field Plugin the remove the color cast and the vignetting. Once you have a good profile image the plugin works very well.
Filmy i say. I just shot a roll with my 50mm F0.95 with an old Canon 7 and it just took me back by years to understand light and shutter speed. My First roll had 4 pictures rightly exposed even with that small light meter and thats when you realize how much we have progressed.
I am back with a new roll and learning lights the right way and its going to be a fun journey, wasted exposures and a whole lot of printing before i can get to a point of knowing, this light outside means this aperture and this shutter speed.
I like the above shot because this is exactly how that film looks like on a matte print.

Interesting. On my A7 the lens works pretty well, but I would like to improve it a bit. I will try the plugin. Any tips for making a profile?
It took me a lot of trial and error before I was able to make a good profile for the lens, The instructions for the Flat Field plug in say you need to create a new profile for each lighting condition and aperture setting. I never found that to be necessary.
What worked for me to take a large plain white sheet of paper and set it up the shade with no direct lighting or shadows falling on it. Then I focused the lens at 1meter at F/8 and overexpose the image by two stops. (I tried everything from 0 to 4 stops, but two worked the best). After imported into LR, it has to be converted to DNG to use the plug in. Once it was in LR, I adjusted the brightness to just below clipping, cleaned up any a few dust spots and set the white balance to get the image as close to a natural white as possible. Then I exported it as another DNG file to use only with the FF plugin.
Works perfectly for me. When I use the CV12mm I found it works best if I just set it on F/8 and set the focus point at about 1m. Essentially everything is in focus from 30cm to forever. I am quite happy with the results on the A7r, it is wonderful lens.

Interesting. Could you post some full size examples with the A7r with the settings you describe (f/8, focus at 1m), please?
A few images from a semi impromptu portraits. Her name is Tiffany, a "new" girl friend of a good friend of mine and I never met before. He told me that she was there with him yesterday and asked whether I felt like taking some images of her. I quickly grabbed 3 lenses with me and we went to a local park. We used a car sunshade as the reflector for fill-in and it worked fine for that purpose.
For this kind of photo shoot though, AF lenses work out the best but I wanted to try out that lens on the new A7s although it actually didn't showcase its low light capabilities. Oh, well .
Wonderful set of images!
